N32G003F5S7

The N32G003 series microcontrollers feature a 32-bit ARM Cortex-M0 core with a maximum operating frequency of 48MHz, integrating up to 29.5KB Flash and up to 3KB SRAM. The devices incorporate one high-speed AHB bus, one low-speed peripheral bus APB, and a bus matrix, supporting up to 18 general-purpose I/Os. They provide a rich set of high-performance analog interfaces, including one 12-bit 1Msps ADC with up to 9 external input channels and one high-speed comparator, along with multiple digital communication interfaces comprising 2× UART, 1× I2C, and 1× SPI. The N32G003 series operates reliably over a temperature range of -40°C to +105°C with a supply voltage of 2V to 5.5V, offering multiple low-power modes to meet the requirements of low-power applications. The series is available in 20-pin package options. The N32G003 series microcontrollers are well-suited for a wide range of applications, including low-power e-cigarettes, security systems, smart home devices, motor control, and power management systems.
